Abstract
This decade has seen rapid developments in infrared light sensing and imaging, utilizing innovative materials and deliberate structural designs. Organic semiconducting materials are promising in the next-generation infrared sensing applications due to their unique properties including solution processability, tunable optoelectronic property, and biocompatibility. This Spotlight aims to provide a snapshot of the recent advances in organic infrared light detection technology, specifically for wavelengths beyond 1000 nm, focusing on performance enhancements and new function realizations. Several innovative proof-of-concept demonstrations illustrate the benefits of the rapidly developing organic infrared technology. Finally, we discuss the challenges and perspectives of organic infrared technology.
